Despite clear associations between vitamin D deficiency and obesity and/or type 2 diabetes, a causal relationship is not established. Vitamin D receptors (VDR) are found within multiple tissues, including the brain. Given the importance of the brain in controlling both glucose levels and body weight, we hypothesized that activation of central VDR links vitamin D to the regulation of glucose and energy homeostasis. Indeed, we found that small doses of active vitamin D, 1,25D3 (calcitriol), into the third-ventricle of the brain improved glucose tolerance and markedly increased hepatic insulin sensitivity, an effect that is dependent upon VDR within the paraventricular nucleus of the hypothalamus.
In addition, chronic central administration of 1,25D3 dramatically decreased body weight by lowering food intake in obese rodents.
Our data indicate 1,25D3-mediated changes in food intake occurs through action within the arcuate nucleus. We found that VDR co-localized with and activated key appetite regulating neurons in the arcuate, namely pro-opiomelanocortin neurons (POMC). Together, these findings define a novel pathway for vitamin D regulation of metabolism with unique and divergent roles for CNS VDR signaling. Specifically, our data suggest that vitamin D regulates glucose homeostasis via the paraventricular nuclei and energy homeostasis via the arcuate nuclei.

Overview Diabetes and vitamin D contains the following summary
- Diabetes is 5X more frequent far from the equator
- Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
- Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
- Sedentary people get less sun / Vitamin D
- Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
- Elderly get 4X less vitamin D from the same amount of sun
Elderly also spend less time outdoors and have more clothes on - All items in category Diabetes and Vitamin D
553 items: both Type 1 and Type 2 Vitamin D appears to both prevent and treat diabetes
- Appears that >2,000 IU will Prevent
- Appears that >4,000 IU will Treat , but not cure
- 90% less T2 Diabetes in the group having lots of Vitamin D
- Appears that Magnesium helps both Prevention and Treatment
- Many diabetics would be better treated if Gut-Friendly Vitamin D were used

*Overview Obesity and Vitamin D contains the following summary
- FACT: People who are obese have less vitamin D in their blood
- FACT: Obese need a higher dose of vitamin D to get to the same level of vit D
- FACT: When obese people lose weight the vitamin D level in their blood increases
- FACT: Adding Calcium, perhaps in the form of fortified milk, often reduces weight
- FACT: 168 trials for vitamin D intervention of obesity as of Dec 2021
- FACT: Less weight gain by senior women with > 30 ng of vitamin D
- FACT: Dieters lost additional 5 lbs if vitamin D supplementation got them above 32 ng - RCT
- FACT: Obese lost 3X more weight by adding $10 of Vitamin D
- FACT: Those with darker skins were more likely to be obese Sept 2014
- OBSERVATION: Low Vitamin D while pregnancy ==> more obese child and adult
- OBSERVATION: Many mammals had evolved to add fat and vitamin D in the autumn
- and lose both in the Spring - unfortunately humans have forgotten to lose the fat in the Spring
- SPECULATION: Low vitamin D might be one of the causes of obesity – several studies
- SUGGESTION: Probably need more than 4,000 IU to lose weight if very low on vitamin D due to
risk factors such as overweight, age, dark skin, live far from equator,shut-in, etc. - Obesity category has
